Abstract: 618,702. Screwing- up nuts &c. AKTIEBOLAGET ATLAS DIESEL. Nov. 11, 1946, No. 33495. Convention date, Nov. 13, 1945. [Class 83 (iii)] In an impact. wrench comprising a rotary hammer engaging, by clutch teeth, an anvil from which it is disengaged on excessive torque by an axial movement, the hammer member is forced axially away from a turning member towards the anvil by independent pressure medium actuated means acting with one end surface on one member, and forming with the other member a pressure medium cylinder. As shown, the wrench is driven by a pneumatic motor within the part 2, Fig. 1, and drives a rotary member 24. The hammer member 4, which engages the anvil 5 by clutch teeth 10, 11, permitting limited relative motion, is axially movable on a stem 12 formed on the anvil, and is provided with an upward extension 31 formed with sloping faces 29, 30, Fig. 2, between which. and similar sloping faces 25, 26 on the driving member 24, balls 27, 28 are provided. The hammer is formed with a cylindrical cavity 13 in which rides a free piston 14, compressed air being supplied to the cavity through a duct 16 in the stem 12 connected to a cross-duct 17 leading to an annular groove 18 supplied by a duct 19 in the housing wall; the duct 19 leads from the main supply through an adjustable reducing valve 22 and a main control valve 26. 35 is a reversing valve for the motor. As the torque increases the inclined surfaces 25, 26 separate from the surfaces 29, 30, as shown in Fig. 3, and the hammer member rises till the teeth 10, 11 disengage; the pressure within the cavity 13 causes the teeth to engage after slight relative rotation, the anvil receiving a hammer blow. In a modification, the turning member and hammer are connected by spaced links. The turning member may also be driven electrically or mechanically.

Title: Improvements in or relating to machine starting and stopping mechanisms
IPC: F16D67/02
Filed: 1935-12-04
Abstract: 466,784. Gearing for stopping and starting machinery. BRITISH UNITED SHOE MACHINERY CO., Ltd., BATES, A., and BARKER, W. A. Dec. 4, 1935, No. 33554. [Class 80 (ii)] One end of a brake band 7, encircling a disc 5 secured to the shaft 3 of a cutting-out press adapted to be driven from a pulley 1 through a spring-urged clutch dog 79 controlled by a wedge arm 73 secured to a spindle 55 journalled in the machine frame, is secured to a pivoted arm 49 connected by a link 51 to an arm 53 secured to the spindle 55. The arm 73 carries a spring-loaded trip lever 69 co-operating with a manually-controlled arm 57 journalled on the spindle 55 and with a cam 83 on the shaft 3. As the arm 73 is raised, by depressing a handle 63 linked to the arm 57, to allow the clutch to engage, the toggle formed by the link 51 and arm 53 is broken, thereby relieving the pressure of the band 7 against the disc 5. As the shaft 3 rotates, the cam 83 operates to disengage the lever 69 from the arm 57, the arm 73 is depressed by a spring 75, the toggle is straightened, and the clutch disengages towards the end of one revolution. The other end of the band 7 is secured to a pivoted arm 9 connected by an adjustable link 19 to one arm of a bell-crank lever 29, the other arm of which is linked to one arm of a lever 37, the other arm of which is linked to the vertically-movable ram 45 of the machine. Thus, as the ram moves downwards, the band is slackened further. As the ram moves upwards, the toggle 51, 53 being at this time in straightened condition, the band is tightened on the disc and the machine is brought to rest at the top of its stroke. To prevent rebound of the arm 73, the latter may be connected by a rod to a pivoted arm extending beneath and engaging a cam secured on the shaft, the cam being so formed that it holds the arm 73 in depressed condition until the clutch has been disengaged and the brake has been applied but releases the arm just before the shaft stops. Specification 22023 /05, [Class 80], is referred to.

Abstract: 520,121. Making washers. GUEST, KEEN, & NETTLEFOLDS, Ltd., and CHAPPUIS, J. A. Nov. 18, 1938, No. 33611. [Classes 83 (ii)] and 83 (iv)] Coiling; forging; shearing adjuncts. - A wire is coiled and severed into rings which are flattened to form washers. The wire is fed between a conicallyholed sleeve 48 rotated by gears 42 from a power-shaft 40 and a non-rotated conical man drel 57 axially pressed by an adjustable spring 64. The wire is close coiled and passes along a tube 70 to a pitch guide 78 in which the turns are separated. A blade 84 on a shaft 88 is oscillated by an arm 91 on a slide 24 to shear one or two turns of wire against a flat face on the guide 78. A spring- pressed pin 92 restores the blade During shearing the coil in the tube 70 is subjected to torsion and the end of the coil, when freed by the blade, snaps into position for the next severing operation. A transverse slide reciprocated by a cam on the shaft 40 carries spring- pressed fingers which feed the wire ring from the shears to a die 119 co-operating with a punch 118. Reciprocation of a slide 23 flattens the ring in the die 119. The ring is then ejected by a plunger 124 moved by a cam-actuated lever 32.

Abstract: 635,203. Reversing records on phonographs. MATARAZZO, G. Dec. 18, 1945, No. 34218. [Class 40 (ii)] A device for turning over records on the turntable of a phonograph at the end of a record, consists of a horizontally mounted rod 1 which has keyed to it two slidable arms 3 having resilient end members 22, 22<SP>1</SP>, which grip the record at diametrically opposite points when the arms 3 are drawn together, and which are rotated through 180 degrees when the arms 3 are raised above the turntable by rotation of the rod 1. The arms 3 are drawn together by links 11 connected to a disc 9 which is rotated by means of a system of levers 12, 13, 15, Fig. 3, under the influence of a cam 17, after which the rod 1 is rotated by a crank 32 so that the arms 3 are raised. The raising of the arms 3 causes a link 28, connected to an offset part of a gear-wheel 26, to rotate said gear-wheel 26 a small amount, thereby causing the resilient end member 22 to be turned 180 degrees in an opposite direction, by means of the gear-wheel 23, spring-loaded pawl 25 and ratchet-wheel 21. During lowering of the arms 3 the direction of rotation of the gear-wheels is reversed, but no rotation of the member 22 occurs because the pawl 25 slips back over the teeth of the ratchet-wheel 21. A similar, but oppositely directed pawl and ratchet on the opposite arm. 3, positively prevents the members 22, 22<SP>1</SP> turning backwards while the arms 3 are lowered.

Abstract: 507,219. Gas detectors; switches. MENOZZI, G. Dec. 10, 1937, No. 34264. Addition to 480,335. [Class 1 (i)] [Also in Group XXXVII] In the inflammable-gas detector of the parent Specification, which is of the type in which a differential gas thermometer having one bulb surrounded by a catalyst is provided with electric contacts operating a signalling circuit, one or more of the following further improvements is or are embodied. As the expansion medium in the bulbs there is used a saturated vapour, or a gas under pressure. The movement of the mercury to close the circuit is facilitated by a conical expansion of the capillary, Fig. 1, and/or by sealing the wires into the glass at a point remote from the point of contact, Fig. 11, to avoid distortion of the capillary. Instead of a straight tube a U-tube may be used provided that the mercury extends over only a small segment of the bend. The capillary may be extended into the bulbs or constricted-near its ends 5, Fig. 11, to prevent spilling of the mercury. The bulbs may be covered with a thin layer of heatconducting material. The heating of the non-catalytic bulb when the circuit is closed, in order to give an intermittent signal, may be effected by an internal resistance 2, Fig. 6, which may be regulated by a shunt 4, or by an external resistance wound found the bulb. Where there are equal lengths of wire in each bulb as shown in Fig. 11, that in the catalytic bulb may have a heat-insulating covering 4, or may be partly shunted by an external variable resistance.
